How do I add a dynamic text file to a button in ActionScript 3?

[Guest]

Okay. I am trying to load different .txt files on the screen with each button click. I am in my first flash class and have only grasped a little bit of actionscript. If you are proficient in actionscript here is my code.

the button names are: bberk_btn apost_btn phales_btn
the text file names are: bberk.txt apost.txt phales.txt

I have no idea how to connect the text files to the function of each button!
HELP!!!

var content_req1:URLRequest = new URLRequest("text/hales.txt");
var content_ldr:URLLoader = new URLLoader(content_req1);
content_ldr.addEventListener(Event.COM... onComplete1);

function onComplete1(event:Event):void {
about_txt.htmlText = event.target.data;
}

var myLoader:Loader = new Loader();
myLoader.load(new URLRequest("images/phalescpy.jpg"));
addChild(myLoader);
myLoader.x=277.2;
myLoader.y=195.2;

function myhales(event:MouseEvent):void {
myLoader.load(new URLRequest("images/phalescpy.jpg"));
myLoader.x=277.2;
myLoader.y=195.2;

}
function mypost(event:MouseEvent):void {
myLoader.load(new URLRequest("images/apost.jpg"));
myLoader.x=277.2;
myLoader.y=195.2;
about_txt.htmlText = ("text/apost.txt");
}
function myberk(event:MouseEvent):void {
myLoader.load(new URLRequest ("images/bberk.jpg"));
myLoader.x=277.2;
myLoader.y=195.2;
}
hales_btn.addEventListener(MouseEvent.... myhales);
post_btn.addEventListener(MouseEvent.C... mypost);
berk_btn.addEventListener(MouseEvent.C... myberk);

Although the help implies this should work, and I've seen it written in a book to do things this way, it's not how I do things:

var content_req1:URLRequest = new URLRequest("text/hales.txt");
var content_ldr:URLLoader = new URLLoader(content_req1);
content_ldr.addEventListener(Event.COMPLETE, onComplete1);

Instead, try:

var content_req1:URLRequest = new URLRequest("text/hales.txt");
var content_ldr:URLLoader = new URLLoader();
content_ldr.addEventListener(Event.COMPLETE, onComplete1);

content_ldr1.load(content_req1);

What I'm trying to do is add a function to each button telling it to load a different external text file.

I tried to do what you asked me to and an error message comes up.

1120: Access of undefined property content_ldr1.

I don't know much about actionscript.

You must define the var at the top level

var content_ldr1:URLLoader ;

Not sure I understand...

another error message:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at about_fla::MainTimeline/about_fla::frame1()

I just want the external text files to be connected to the functions of the buttons:  bberk_btn; apost_btn; phales_btn

In that case I recommend you to read about the navigateToURL in the documentation files to better understand how it works and how to use it my friend.
